IMPROVEMENT IN HORSE-POWERS.

Specification forming part of Letters Patent No. 223,197, dated December30, 1879; application filed October 21, 1879.

efficient the ordinary machine or mechanism in which the power of horsesis exerted to drive other machinery.

The invention consists in a novel arrangement of a tongue anddouble-tree, in combination with the sweep or lever of a horse-power,whereby greater leverage may be obtained within a given circle.

In the drawings, A represents the frame of a building in which thehorse-power is located. B is the king-post; G, the levers fixed in thekin gpost B and radiating therefrom.

D is a scantling or tongue, having one end insertedin a mortise in orotherwise fastened to the lever O and the other end fastened to thesupport E, which, itself has one end fastened to the king-post B, whilethe other end serves as an axle for the wheel F.

G is a double-tree, secured on the scantling or tongue D for theattachment of the horses.

In an ordinary horse-power, intended,- as is this one, especially forginning cotton, the double-tree is attached to the lever O, as shown indotted lines at E, Fig. 1, at apoint, it will be seen, nearer theking-post B than is the point of attachment of the tongue or scan tlingD, to which is attached the double-tree G, for the scantling or tongue Dis not used in the ordinary horse-power; hence the point of attachment Hto the lever U is the most convenient, and is placed as far out towardthe end of the said lever G as the side of the building will permit forthe uninterrupted or free movement of the horses.

On a floor thirty-two feet square, which is the usual dimension of aginning-room, the outer edge of the path traveled by thehorses, hitchedto the lever Gin the usual manner, represents a circle of thirty feet indiameter, the said levers C being fifteen feet long from the center ofthe kin g-post B, and the point of the doubletree attachment beingthirteen feet from the center of the king-post B.

In this improved arrangement the point of attachment to the lever O ofthe scantling or tongue D is fourteen and one-half feet from the centerof the king-post B, and, as it is obviously to this point of attachmentthat the power is applied under the present-arrangement, it will be seenthat a gain of one and one-half foot more leverage is made on each leverC, so that within the limits of a circle of thirty feet in diameter asmuch effective power can be applied as within a circle of thirtythreefeet in diameter by the old method, three feet of aggregate leveragebeing gained by this new arrangement over the greatest practicableleverage that can be had by placing the horsesin front of the lever O,as shown at H.

As a substitute for the wheel F that supports the end of the support E,a brace may connect the outer end of the said support E with theking-post B.

Having thus described our invention, what we claim as new, and desire tosecure by Let= ters Patent, is-

In horse-powers arranged in buildings A, the combination, with the sweepO, of the tongue D, provided with devices for attaching the horses, andthe sustaining-bar E, the latter supported on wheel F at one end, andattached at the other to the king-post B, as shown and described.
